MEANS FOR TACKING ON CARD-CLOTHING.

Specification of Letters Patent.

Patented Aug. 6, 1907.

Application filed November 13, 1906. Serial No. 343,196.

To all whom it may concern:

Be it known that I, ADDISON ARNOLD, a citizen of the United States,residing at Charlotte, in the county of Mecklenburg and State of NorthCarolina, have invented a certain new and useful Means for Tacking onCard-Clothing, of which the following is a specification reference beinghad therein to the accompanying drawing.

This invention relates to means for tacking on card clothing uponcylinders, doffers or any kind of reels using card clothing for cardingcotton, wool, flax, henip or any other carding, brushing or nappingwhere fillet card clothing is used.

In carding machines, the cylinders require about two hundred and sixtyeight feet of two inch clothing to cover the same; there are about threehundred wooden plugs to a cylinder and a tack must be driven through theclothing into each plug. As ordinary round flat headed tacks are used,approximately a quarter of an inch square of the teeth of the clothingis spoiled and rendered worse than useless for each tack, Furthermoreholes or voids are thus formed in the teeth of the clothing which fillwith the material, forming balls or wads which pass'on to the doffer,etc. and impair the product of the machine.

The object of the present invention is to provide means whereby theobjections above noted may be practically overcome, the card clothingbeing fastened to the cylinder or doffer without injuring or displacingany of the teeth, the clothing being left in perfect condition andproducing much better results as a consequence thereof.

With the above and other objects in view, the nature of which will morefully appear as the description proceeds, the invention consists in thenovel construction, combination and arrangement, herein fully described,illustrated and claimed.

In the accompanying drawings:Figure 1 is a plan view of the device ormachine of this invention, showing also a section of card clothingpassing therethrough and secured by tacks of several kinds. Fig. 2 is aside elevation of the same illustrating the manner of using theapparatus. Fig. 3 is a longitudinal section through the same. Fig. 4 isa cross section thereof. Fig. 5 is a perspective view of one of theplows. Figs. 6 and 7 are detail views of two kinds of tacks employed infastening the card clothing in place. Fig. 8 is a sectional elevation ofthe set used for driving the tacks.

Referring to the drawings 1 designates a section of card clothing havingthe usual teeth 2. This clothing may be of any width and, as is wellunderstood. is put on the cylinder in strip form. the strip passingaround the outer surface of the cylinder and being fastened thereon.

In carrying out the present invention I employ a casing 3, which may beof sheet metal or any suitable material, and which embodies oppositelyarranged parallel sides 4 and a connecting bottom 5 at right angles tothe sides, as best shown in Fig. 4. Under the preferred embodiment ofthis invention the end portions of the sides 4 are low, that is to saythey do not extend very high, while the middle portions of the sides arerelatively high and form a housing for the guide, hereinafter described.

The guide 6 fits between the sides of the casing and is fastened inplace by one or more screws 7 or their equivalent. Said guide is in theform of a block which is provided in the bottom thereof with a series ofparallel ways or grooves 8, in which a corresponding series of plows 9are arranged to slide freely lengthwise of the card clothing. Each ofsaid plows is constructed and shaped as shown in the detail view, Fig.5, where it is seen to comprise the elongated body the bottom edge ofwhich is brought to a fine edge, as shown in Fig. 4 so as to wedge itsway between the rows of teeth of the clothing. The body of the plow isslotted longitudinally as shown at 1.0, and passing through all of theslots of the several plows is a stop 11, shown in the form of a roundpin the ends of which are fast to the sides of the casing 3. This steppermits the plows to be moved lengthwise but arrests their movement inone direction and acts to line up the plows as the clothing passesthrough the casing onto the cylinder or doffer as the case may be, theclothing acting on the plows with sufiicient friction to drag them backto place in readiness for the tacking on operation, to be hereafterdescribed. Each plow 9 is further provided with a tail portion 12 of aheight not to extendmuch above the tops of the teeth of the clothing,and the extremity of said tail is split or forked, while the arms orblades 13 of the fork are givenv an upward flare and divergence. Thebottom edge of the tail part is also cut away as shown at 14. so thatthe space between the blades of the fork is left open at the bottom aswell as the top, thus adapting the tacks, shown in Figs. 6 and 7 to beinserted between the blades of the fork at the top and pushed downwarduntil they enter the body of the card clothing between the rows of teeththe tops of which have been spread apart by the plow.

The preferred form of tack is shown in Fig. 6 and designated 15, saidtack embodying a long, narrow parallel-sided head the thickness or widthof which is about one twenty-fourth. of an inch, the distance betweenadjacent rows of teeth on the clothing. Instead of the tack shown inFig. 6, a double tack 16, of staple form, such as is shown in Fig. 7 maybe used, the same width of head being retained so that the tack headwill lie between the bases of the teeth and not deflect or bend the sameto the injury or impairment of the clothing.

In connection with the machine described, and the tacks referred to, Iemploy a tack set or driver 17, the end of which is reduced until it isquite narrow and hollowed out or concaved as shown at 18 to fit over thetack head and prevent the set from slipping in the driving operation. Atthe other end the set is provided with a handle 19 in line with thelongitudinal axis of the recessed point 18 of the set, so that byholding the handle 19 directly in line with the length of the plows, thehead of the tack is sustained in proper line while driving the same.

In operation, the machine is held over the cylinder or dofier, and thelatter turned until the split ends of the plows come over the woodenplugs of the cylinder. The cylinder is then stopped and the requirednumber of tacks are pressed between the blades of the forks into theplugs, through the card clothing. The set 17 is then applied to theheads of the tacks and driven down, the plows being slid out of the way,successively, by the operators linger to permit the set and tack to bedriven home.

The device may, of course be made of any width, and any desired numberof plows may be used according to requirements and the fineness of thecard clothing as regards the number of teeth to the inch. Furthermore,the card clothing may be of any desired width and may be applied to acylinder of any required size.
